Do I need to remove the bumper or fascia to install this?

No. This grille mounts directly to existing factory points on the front end. You'll access it from behind the fascia, but complete removal isn't necessary for most vehicles.

Does this come with mounting hardware?

Hardware isn't confirmed in the specs. Grab your fasteners from the original grille if reusing, or pick up basic hardware from your local hardware store — standard automotive bolts work fine.

Will I need to paint or prep this before installation?

The finish comes ready to mount. If you want a different color or have paint damage, light sanding and a quick spray-over works, but it's not required out of the box.
